Description

An AMP compatible toolbox to help complete WordPress. Core features include:

Security,
Thank You message,
Date information,
Paragraph links,
Heading links,
Table of contents,
Notes and sources (in two lists with post- or site-wide reusable templates),
Reference lists (as a standalone commodity),
Webfont loading.

Notice about Language support: While American English is supported natively, British English support is at 100% (generated). French and Spanish with all sublocales supported by WordPress benefit from internal translation, currently at 18% and 6% respectively. About one in four string instances are in synergy with WordPress Core.

To date, the A.N.R.GHG Publishing Toolkit has still somewhat limited functionality but is already fairly complex. It addresses the challenge to do by HTML and CSS things that used to be done by JavaScript, which was one reason the internet loaded slowly on mobiles and consumed more resources than with AMP technology. So far, the A.N.R.GHG Publishing Toolkit can:

Security

Protect WordPress websites against password leak effectiveness, by hampering the login process depending on the value of a constant defined in a mini-plugin (editable on the hosting platform);
Make that constant configurable so that in multisite networks, individual sites may be toggled independently;
Extend authentication cookie lifespans to a configurable period of time, for example until the day after the next scheduled login rush;
Display the login activation status by icon in the Admin bar;
Blank the login dialog out if it is convenient to access the WordPress Admin area through the hosting platform exclusively.
CAUTION: Shared hosting is prone to being hacked by webshell even if only a single one of the hundreds of websites sharing the same server’s root directory is compromised. Therefore, the A.N.R.GHG Publishing Toolkit’s security feature is efficient only on websites hosted on a Virtual Private Server (VPS) or a dedicated server.

Thank You message

Display a configurable message after posts and/or pages;
Help with activating and configuring the message on a per-page basis in the Post Meta box;
Make available a set of rich text messages configured in the Template editor;
Provide a block to configure an unlimited number of messages right in the post or page.

Date information

Display the last modified date at post/page start or end;
Display the published date at the start or end of pages where WordPress does not display it natively;
Optionally add a freely configurable field about where the post was first published;
Add date meta tags (may be useful if not already added by an SEO plugin).

Paragraph links

Add a fragment identifier in a configurable link prepended to every paragraph and list item;
Use position independent identifiers derived from the content;
Use the custom ‘HTML anchor’ for all paragraphs that it has been configured for, further improving identifier stability;
Keep the identifiers fully localized also when using a non-Latin script, for legible display in the URL bar.

Heading links

Add localized and optionally stable fragment identifiers and hyperlinks to headings.

Number the headings by CSS in appended or prepended position with a backlink to the table of contents;
Replace the appended number with a generic arrow if numbers are not desired next to headings;
List the headings in a table of contents, that the heading numbers link back to;
Optionally collapse and expand the table of contents from the label, also when JavaScript is off;
Insert a table of contents automatically in all posts with a configurable minimum number of headings;
Deactivate the table of contents for a particular post or page in the added Meta box;
Add a table of contents if the Table of contents block is present;
Use a configurable string as an alternative positioner in the Classic Editor to override the configured default position;
Configure its label for all posts in the settings, and for a particular post in the Post Meta box or in the block, or by adding an argument in the code;

Notes and sources

Parse inline notes and sources and display them either as descriptive endnotes or as bibliographic endnotes depending on their delimiters;
Process sources nested in notes;
Show notes and sources in responsive, adaptative and configurable rich tooltips when hovering their inline anchor;
Support six numbering systems including Eastern Arabic digits to help distinguish notes from sources;
Register notes and sources on the fly for reuse across a post or page;
Store notes and sources as templates for reuse across the website;
Display additional text around reused notes and sources;
Handle multiple notes and/or sources reused in a single instance;
Parse the notes and sources delimiters as freely configured also using non-Latin script or punctuation only;
Support switching complement delimiters midway, parsing older posts for the previous ones while the current ones are processed in posts from a configurable ID on;
Save the current delimiters with each post, so that delimiters may be reconfigured at any time and are valid in new posts;
Parse post-specific sets of delimiters configured in the Post Meta box;
Display complements in a number of columns (up to three) configurable for notes and sources separately, and responsively with respect to mobiles;
List complements section-wise at each instance of the block in the Block Editor, or alternatively, of a configurable positioner code in the Classic Editor;
Defer complement lists to the footer of a particular post, or do so for all posts unless specified otherwise;
Post-process the web page to move complement lists from the built-in WordPress default position below the footer to within the footer;
Specify the writing direction in complement lists and anchor tooltips for notes and for sources separately on a per-post basis in the added Post Meta box, or per instance in the block (Block Editor) or the positioner code (Classic Editor);
Display a complement in a new tab or window using its URL even when lists are collapsed by default;
Keep complement lists collapsed except for the target item after clicking an anchor, so as to not distract from the other features and information;
Optionally expand the full list on clicking any anchor as it is useful for ibid notation;

Concept

The A.N.R.GHG Publishing Toolkit aims to be one more Swiss Army knife to help complete any WordPress installation while reducing greenhouse gas emissions in multiple ways:

Thanks to AMP compatibility for a faster, less resource consuming web;
With streamlined processes at its end in a slim code base without external style sheets;
Through its commitment to web hosting with renewable energy ever since the first months;
By developing in a local WordPress stack on a laptop powered with 100% renewable energy from the local grid operator;
Being developed by a vegetalian, because going vegan is the single biggest way to reduce our impact on planet Earth, per Oxford University research and helps terminate animal torture.

Beyond being fully AMP compatible, the A.N.R.GHG Publishing Toolkit’s features for the public pages stay functional where JavaScript is turned off, with one limitation: Expanding the table of contents from a heading backlink requires one click more.

Installation

Security

Shared hosting is prone to being hacked by webshell even if only a single one of the hundreds of websites sharing the same server’s root directory is compromised. Therefore, the A.N.R.GHG Publishing Toolkit’s security feature is efficient only on websites hosted on a Virtual Private Server (VPS) or a dedicated server.

For an additional layer of security, it is recommended to deny access to the wp-config.php file, and to the debug.log file in case there is any. To achieve this, please add the code snippet provided for the purpose near the bottom of the template-wp-config.php file by copy-pasting it from this file in the anrghg/ plugin folder to the .htaccess file in the WordPress root directory.

Requirements

Prior to installing the A.N.R.GHG Publishing Toolkit, please make sure that the PHP memory limit is configured appropriately in the web hosting. The large settings page requires more than 32MB. A too low memory limit results in the failure of important processes: theme updates, plugin updates, editing large posts and pages, and generally in a lot of malfunctioning and buggy behavior in WordPress and other systems.

Safe is to set the PHP memory limit to 256M as a rule of thumb, but many hosting providers throttle it down to 128M. If your plan includes cPanel, more options such as 512M may be available in the “MultiPHP INI Editor” under “Software” in the “Tools” menu on the cPanel home page in your hosting account.

WordPress configuration

The memory limit defaults to 40 megabytes for a single site, 64 MB for a multisite, so it may be necessary to increase this limit, although the A.N.R.GHG Publishing Toolkit is not known for being particularly memory-intensive. Options include 64M, 128M, 192M, 256M, 368M and 512M as the value should match the memory limit set in the website’s hosting. The file template-wp-config.php includes a template for this.

Install process

A. Standard process in the WordPress Admin area

In the Admin menu, navigate to Plugins > Add New;
In the search bar, type ‘anrghg’;
In the search results, spot the ‘A.N.R.GHG Publishing Toolkit’;
Click the ‘Install Now’ button next to it;
Eventually click the ‘Activate’ button showing after installation complete.

B. Mixed process in the WordPress Admin area

Download ‘A.N.R.GHG Publishing Toolkit’ as a .zip file from the WordPress Plugin Directory;
In the Admin menu, navigate to Plugins > Add New;
Click the ‘Upload Plugin’ button next to the page heading;
Click the ‘Choose File’ button;
Choose the downloaded .zip file;
Click the ‘Install Now’ button;
Eventually click the ‘Activate Plugin’ button.

C. By uploading via FTP

Download ‘A.N.R.GHG Publishing Toolkit’ as a .zip file from the WordPress Plugin Directory;
Uncompress the downloaded .zip file;
Switch to an FTP client;
Access the plugins directory;
Make sure the same plugin is not already there, else delete the old one;
Upload the folder anrghg/ resulting from step 2;
Refresh the Plugins list;
Eventually click the ‘Activate’ action link of the ‘A.N.R.GHG Publishing Toolkit’.

Plugin configuration

To activate the security feature, a constant needs to be defined in a mini-plugin. The code is already in the mini-plugin template template-mini-plugin.php.

Once the A.N.R.GHG Publishing Toolkit is installed, it needs to be configured:

Most features are deactivated by default and may be activated individually. To access the settings page, please click the Settings action link of the ‘A.N.R.GHG Publishing Toolkit’ entry in the Plugins list. No menu items and no Post Meta box are added by default. To activate any of these, or the ‘Thank You messages’ or ‘Reference lists’ block, please choose the desired UI elements in the ‘User interface’ section of the Settings page.
Even if the setting to turn a feature on uses the glide-switch design with ON and OFF button symbolic, please be still sure to save the form clicking the Save Changes button at the bottom of the window. Unlike the behavior specified in Android Material Design and SAP Fiori Design, changes require saving the form to become effective.
Several headings or labels may need to be configured to your locale. That may be done on the Settings page, or in the ‘String translation’ pane of a multilingual plugin after saving the Settings page at least once to the database, or using configuration filters as provided in the file template-filter-config.php.
The strings delimiting notes and sources are freely configurable and come also with two presets as suggestions. So do the inner delimiters. Codes needed to materialize positions are configurable too. Most of these configurations are versatile in that the plugin adapts to changes on the fly or mid-way.
In the optionally added Post Meta box, every single section can be deactivated individually. After activating the Meta box, it displays with all elements by default just to make selection easier. Please be sure to switch elements in and out individually as desired in the settings page under ‘User interface’.
Many features may be configured alternatively in a mini-plugin, easy to set up on the basis of the included template template-mini-plugin.php, or especially for theme-specific values, in your child theme’s functions.php, using configuration filters as documented in the file template-filter-config.php. That may be useful to help with adapting the configuration to theme-specific requirements while using multiple themes like in AMP Reader mode.
Configuration filters are currently the only means to configure some features, notably the previous complement delimiters, used in posts and pages with an ID that is less than a configurable number. These filters are documented in template-filter-config.php under ‘Previous delimiters’ and ‘Previous delimiters for tooltips’.
When using a translation manager with a String Translation pane, please be sure to save the Settings page at least once to your database, because translation filters require retrieving the strings in the database.
Adding more hooks is projected for the purpose of filtering the HTML output, much like the style rules may be overridden by Custom CSS that the A.N.R.GHG Publishing Toolkit contains also two storage facilities for: one at the end of the Settings page, and another, independent one for use with a configuration filter.

Register templates post-wide

To reuse a complement already used in the same post, it may be given a name in the first instance like so: [note]a_name[/name]The complement.[/note]. In case of conflicts, post-wide names prevail over site-wide names.

The name start delimiter ([name]) is not used for new complements. Its sole purpose is to delimit names in arbitrary positions.

Register templates site-wide

Complements become reusable site-wide when registered with the ‘Template editor’.

The name of a template may be any Unicode string; the only constraint is to not contain ordinary space.

In the list, existing complements are displayed full height with formatting, and HTML markup may be added directly too if JavaScript is on. If JavaScript is turned off, the source code is displayed, and new complements need to be written in source code as well.

Changes to existing complements can be made directly by editing the list.

Alternatively, a complement may be moved into the editor by clicking the ‘Move into editor’ button next to it, but before doing so, please make sure that TinyMCE is in Visual mode (both methods to set the mode programmatically fail and the one to get/check the mode is missing), as else the editor.setContent() method fails, the content disappears, and the page will need to be refreshed to get the item back instantly.

The ‘Move into editor’ buttons are deactivated for safety when either TinyMCE or the new name text box is not empty.

To help with choosing unique names, the names already in use are displayed in alphabetical order below the new name text box. The data is validated server-side, and if a problem is detected with missing, duplicate or invalid names, a warning will display and the cursor will be set to fix it.

All templates are backed up in a time-stamped file on accessing the list and on saving the form, if this feature is not deactivated in the settings. The backups are located in a subfolder named anrghg/ in the uploads/ folder in your wp-content/ directory.

Reuse complements

Simple syntax: To reuse an already registered complement, put its name as the first, last, or only word in a note or source.

To add more text like a page number, use a space as a separator between the complement name and the added text, like so, where ␣ stands for an ordinary space:

Before (the prepended space is kept): [src]According to the explanation set out on page 10 of␣name1[/src]

After (the appended space is skipped): [src]name1␣, page 10.[/src] or [src]name1␣␣explains it on page 10.[/src] (To have the source followed by a space, two spaces need to be typed.)

Full syntax: Beyond this simple syntax, the full syntax brings the opportunity to add more text on both sides, and to reuse multiple complements in a single instance.

Example: [note]See [name]reusable_one[/name], page 31, and [name]reuse2[/name], chapter 4.[/note]

FAQ

What does A.N.R.GHG stand for?

A.N.R.GHG is the initialism of ‘Act now, reduce greenhouse gasses’.

The dots have been added to help screenreaders spell it as an initialism rather than as an acronym.

The climate crisis requires us to enroll all aspects of our work and lives so that our efforts converge towards addressing the crisis now as a top priority urgency.

The AMP technology contributes to streamlining processes and making the internet less energy-consuming.

Moreover, development and maintenance are powered with renewable energy as well since the developer subscribed to the green electricity option offered by the local grid operator to individual households at a monthly fee of about $2.

Most importantly, the developer is a vegetalian, as avoiding meat and dairy, eggs and fish helps making an end of animal torture and is the scientifically recommended single biggest way to reduce our impact on planet Earth, an Oxford University study assessed.

Why are multiple features crammed into a single plugin?

A number of features like heading links and table of contents, notes and sources or last modified date and published date of pages are interrelated, and solutions using one plugin per feature are suboptimal because of inconsistent identifiers or presentation.

Beyond consistency, among the reasons that further fueled the adoption of an “all”-in-one concept are efficiency and economies of scale, much like what Jetpack is achieving at an incomparable magnitude.

As a result, making individual plugins out of some of the features is not required and would be inefficient. Keeping them all together seems like the best option.

Why are all settings crammed together on a single page?

This way, the settings can be searched for any string using the browser search functionality (Control + F), and all occurrences can be accessed directly. That would be impossible if the settings were grouped by topic under a number of tabs.

The table of contents at the top of the settings page replaces the tab row or column, while allowing for longer, more explicit labels. It can be accessed by clicking the ‘Back to top’ button at the top of the window in a fixed position.

Likewise, the ‘Save settings’ button is constantly visible at the bottom of the window. Clicking it does not require scrolling down to the bottom of the page.

Why do processes fail when this plugin is active?

This issue depends on the PHP memory limit. The large settings page requires more than 32MB. Safe is to set the PHP memory limit to 256M as a rule of thumb, but many hosting providers throttle it down to 128M. If your plan includes cPanel, more options such as 512M may be available in the “MultiPHP INI Editor” under “Software” in the “Tools” menu on the cPanel home page in your hosting account.

The limitations involved by a low memory limit affect plugin updates, theme updates, as well as other actions performed by WordPress and its plugins, for example editing large posts in the Block Editor. Other content management systems are likewise impacted by low memory limits such as 32M, that may be the default settings value in shared hosting.

How about using jQuery?

As the jQuery JavaScript library is not fully AMP compatible, features like tooltips, expand/collapse and scrolling back and forth do not use jQuery. Another reason is that when using jQuery, and JavaScript is turned off in a browser, these features are broken in that browser. Yet another reason is bad user experience as links to end notes are either unavailable, or available hard links cannot be opened while the relevant list is collapsed. Moreover, using jQuery prevents from saving a fully functional copy of a page. These frustrating issues outweigh the benefits of using jQuery.

Regardless, for end notes there is another plugin out there that uses jQuery by default and offers the ability to opt out: The Footnotes plugin, although closed since 2022-11-14, is consistently recommended in 2023, and it is compatible with the Twenty Twenty-Three theme. It can be installed as a .zip file following process B after downloading its latest version directly from the WordPress Plugin Directory, as it is two or three times a day on average per current stats, or from the latest backup of its full Plugin Directory page in the Web Archive.

However, since the Footnotes plugin is unmaintained, it may basically become a target of exploiting security vulnerabilities. That is why reading the abandonment statement made by its last developer, or its archived version, is strongly recommended.

Can I use various themes alongside?

Yes, using configuration filters, that have precedence over settings values from the database, each theme can have specific settings values stored in its child theme’s functions.php, so that sensitive values may be fine-tuned in accordance with particular layout options, while values that are constant across themes may still be configured in the settings page and called from the database.

The A.N.R.GHG Publishing Toolkit includes a template file called template-filter-config.php documenting all filters available so far (while process filters are being added as documented in template-filter-output.php).

How to keep configuration filters when switching themes?

As a stable place to add configuration filters and process filters, a mini plugin is convenient. A mini plugin template is included in the plugin folder. To use it, just move it out of the folder, eventually rename it, optionally place it in a new folder, then make it a plugin by deleting the percent sign in front of the %Plugin Name: field label, and activate it after refreshing the Plugins list.

Why are the strings not in the translation pane?

For multilingual plugins to show the strings in the translation pane and to work effectively, the translation keys must be present in the database. To achieve this, please access the plugin’s settings page and click the ‘Save Settings’ button at the bottom of the window.

After this, all translatable configuration values will show up in the translation pane, even those that are not yet configurable on the settings page.

Are rich-text category pages supported?

Yes, category pages are supported through the term_description hook, so that all features are fully functional as configured.

When using the A.N.R.GHG Publishing Toolkit, category pages are unaffected by the filter that would usually delete HTML markup, and may be drafted like pages in the Block Editor, kept as drafts, and copy-pasted from the Code Editor to the term description window. Eventual leftover block markup is removed at runtime.

Are custom post types supported?

Yes, the A.N.R.GHG Publishing Toolkit supports all post types applying the filters hooked on the the_content hook; for example, custom post types of WooCommerce like product pages are supported through this hook. Additionally it supports popups from Popup Maker (Code Atlantic) by hooking on pum_popup_content, and from Popup Builder (Sygnoos) by hooking on sgpbSubscriptionForm.

Beyond, it processes a configurable list of additional hooks. The only requirement for a content type is to apply filters on the content, using whatever hook. The name of that hook needs to be filled in an input field on the settings page, or in the configuration filter found among the templates under “Support alternative content hooks.” Multiple hook names are comma-separated.

For convenience, a dedicated hook is also available, that the A.N.R.GHG Publishing Toolkit adds filters to for subsequent application to a given content by calling the WordPress apply_filters() function:

$content = apply_filters( 'anrghg_content_filter_hook', $content );

Are custom fields supported?

Wysiwyg fields added using Advanced Custom Fields are optionally processed for inline complements and other features as well, and complement lists are appended at the bottom of each field. That can be deactivated so that these fields would be processed as part of the post content if displayed accordingly.

Alternatively, when the hook that the field applies filters to is known, its name may be added to the content hooks in the settings.

The A.N.R.GHG Publishing Toolkit also adds numerous fields, among which the ‘first published date’ that will be displayed if its prefill has been changed in the Post Meta box.

Can I use shortcodes instead of blocks?

Yes, sort of. The A.N.R.GHG Publishing Toolkit does not rely on the WordPress Shortcodes API, because Shortcodes cannot be used to reliably process notes and sources. For example, the scheme is disabled in forms set up using the WPForms plugin. Also, available options are too restricted and may exclude your preferred ones; so, not being internationalized, the shortcode API fails on Non-Latin shortcodes; and not being versatile, it cannot process delimiters made of brackets, braces, parentheses or other punctuation characters only.

Additionally, registered shortcodes are removed from other usages such as schema and meta descriptions for SEO. That is appropriate for most shortcodes, but may not be desirable for sources: Stripping off these complements may convey a misconception of the content as containing unsourced statements, and thus harm the website’s reputation.

On the other hand, the A.N.R.GHG Publishing Toolkit is fully compatible with the Classic Editor relying on shortcodes: Instead of using the blocks, fully configurable strings like [anrghg_toc] and [/anrghg_section] may be manually inserted, both with optional arguments.

Can the appended message be edited in rich text?

Yes, by configuring it in the Template editor. Then insert its name in the input field on the settings page or as a return value in the configuration filter.

Can I use the post title in the appended message?

Yes, to insert the title of the current post or page, please insert the placeholder %s in the template text.

Why does the link to a code block not show up on hovering the code?

As the code block is scrollable, its overflow is hidden, so any protruding elements like the paragraph link are cut off. To work around the issue, code blocks are wrapped into a paragraph, but this paragraph becomes two paragraphs due to the block level code block, and the first paragraph stops before the code. That is why the link shows up only when hovering the area in the margin before the start of the code.

Does adding a paragraph break links to other paragraphs?

In most cases not, because the identifiers that the A.N.R.GHG Publishing Toolkit assigns are content-based, both for Latin and for non-Latin scripts. These are URL-encoded, much like WordPress derives slugs from titles.

The main case where numbering is added is to disambiguate identical headings.

As paragraphs are unlikely to have identical beginnings spanning over more than 200 characters—the length that fragment identifiers are shortened to before cleaning up truncated last words—, every paragraph has a unique stable identifier, unless the underlying text is modified.

How to edit headings or paragraph starts without breaking links?

By giving them an “HTML anchor” in the Block Inspector. For each heading, paragraph or list item, the A.N.R.GHG Publishing Toolkit uses its existing “HTML anchor” in the first place. Only if none is configured, it proceeds to derive a fragment identifier from the content.

If a URL with a content-based fragment ID is in use prior to editing the underlying content, then the existing ID may be grabbed in preview mode and copy-pasted into the “HTML anchor” input field without the prepended post ID, as this number is always prepended automatically to any ID.

Prepending the post number helps ensure that each ID is unique across the website, in support of the infinite scroll (AJAX autoload) feature.

How to position the table of contents without the block?

That is done by typing [anrghg_toc] or any bracketed string that this code is configured to.

Arguments between the code name and the closing bracket are also supported, and both names and values are designed for ease of input. Argument names are preceded by a space and start with an underscore. Values are delimited by vertical bars. The equals sign may or may not be space-padded:

Label tailored to the instance: _1=|Contents of ‘%s’|, where %s is replaced with the post title (for tables after the post);
Alignment: _2=|0| or _2=|center|, or _2=|-1| or |left|, or _2=|1| or |right|;
Collapsing behavior:_3=|-1|for expanded (and collapsible), or_3=|1|for collapsed (and expandable), or_3=|0|` for uncollapsible.

Why are level 1 headings supported?

Stray level 1 headings do indeed have a negative impact on search engine rankings. Using H1 outside the post title is strongly discouraged. Also the heading formatting defaults to H2 in the Block Editor, while in the Classic Editor the shortcut Shift + Alt + 1 is deactivated. We are warned.

Yet multiple level 1 headings are in current use outside the web, so the support for H1 is consistent with standard word processing user experience. And when the .docx or .odt formats are converted to WordPress, headings are usually not downgraded (despite they should be), to prevent H6 from being degraded to paragraph level, since custom H7 markup is not well supported by the web.

The A.N.R.GHG Publishing Toolkit supports level 1 headings if they are present in an article body, because H1 formatting is available in WordPress, that inherits it from TinyMCE where it makes actual sense, as TinyMCE is also used in systems that may not feature an extra field for the page title.

Do the added fragment IDs interfere with my custom anchors?

No, because the “HTML anchor” configured in the Block Inspector is added right inside the element’s start tag, while the A.N.R.GHG Publishing Toolkit adds its IDs in an extra span.

Can I have heading anchors also in a linked PDF?

Yes if they are built-in; but these fragment identifiers are like scroll instructions. More universally, using URL parameters, scroll instructions may apply to any PDF opened in a browser:

To scroll to the page, add a hash to the PDF’s file name in the URL, then page= and the page number:

domain.tld/folder/your-file.pdf#page=123

To scroll to a heading in the page, append an ampersand, then zoom= and three comma-separated numbers: first the zoom factor in per cent (a zero is interpreted as 100%), next the X offset in pixels, then the Y offset. Basically you only need the third number, a best-guess determined by trial-and-error or measuring pixels so that the target heading displays a little below the upper viewport edge:

domain.tld/folder/your-file.pdf#page=123&zoom=0,0,700

How is the table of contents expanded?

The A.N.R.GHG Publishing Toolkit’s table of contents features a CSS-only transition when expanding or collapsing.

For AMP compatibility, JavaScript is avoided on public pages when the same behavior is not implementable in the AMP framework.

What is the lone heading after the table of contents label?

That happens after clicking a heading number while JavaScript is turned off, because expanding the table of contents from heading numbers relies on JavaScript (either in AMP or Vanilla); else, the scrolling wouldn’t work. So, without JavaScript, the target list item displays alone thanks to CSS, and the table of contents waits for its label or twistie being clicked to expand by CSS.

There is a small likelihood for the same to happen while JavaScript is on. On AMP pages, the related style rule is always valid, but after clicking a heading number (which is when it would come into play) it is overridden by another one, activated using the AMP framework. Reloading the page in that state would result in a lone heading as pointed in the question.

How are complement lists expanded?

The A.N.R.GHG Publishing Toolkit’s complement lists are expanding or collapsing by CSS only, with a slight transition.

For AMP compatibility, JavaScript is avoided on public pages when the same behavior is not implementable in the AMP framework.

Why are complements not soft-linked?

Compared to hard links, soft links have multiple downsides, while the disadvantage of using hard links is easily mitigated by hitting the backbutton instead of clicking backlinks. A configurable plain tooltip on hovering a backlink suggests this workaround, that will remove the anchor click from the browsing history.

Moreover, hard links allow accessing complements from outside, as they are the precondition of using the :target CSS selector to display the desired complement only, without expanding the whole list. That scheme always helps your visitors not be distracted from the other features and contents often displayed after or before the complement lists, notably the social icons and related posts. Your visitors may see these features as soon as looking up a complement in the list, as an alternative to checking it out in its tooltip.

Thanks to using hard links, no script is used, and since expanding and collapsing complement lists and tables of contents from their label is done without JavaScript likewise, the A.N.R.GHG Publishing Toolkit’s features are fully functional in browsers where JavaScript is turned off (and AMP actions won’t work either). Additionally, for convenience, CSS-based scroll offset as well as smooth scrolling are supported, too.

Are identical complements combined?

Yes, optionally identical notes or sources are combined into a single item with a single number. Thanks to using hard links, scrolling back up is performed by using the backbutton. For reference, all links to the instances where the complement is used are enumerated in a tooltip on hovering the complement number in the list.

Notes and sources are only combined section-wide. Identical complements occurring in several sections of a post or page appear once in every related list.

What are the numbering options for notes and sources?

Beside the standard Western Arabic digits, notes and sources may be numbered using Eastern Arabic digits, or be numbered each in a distinctive manner among Roman and Latin numerals, both available in lowercase and uppercase.

Are long complements truncated for display in tooltips?

Never, because the tooltips are styled in a way that truncating is unnecessary. When exceeding a configurable number of characters, the tooltip displays full-width even on desktops, and if it would exceed a configurable maximum height, it becomes scrollable.

That said, the A.N.R.GHG Publishing Toolkit supports a dedicated tooltip text, similar to WordPress’ manual excerpt feature. If the (configurable) [/view] delimiter is present in the complement, the text before is displayed as tooltip text, while the following text represents the complement in the list. This is linked to from the end of the tooltip, and from anywhere in the tooltip by delimiting the link text with [link] and [/link], or any delimiters these are configured to.

Can complements be nested?

Yes, provided that the nested ones are sources, and those they are nested in are notes. Notes cannot be nested in sources, nor a source in another source. Only these three use cases are supported:

[note][/note];
[src][/src];
[note][src][/src][/note].

Each note may include several sources.

Can I start using other delimiters from now on?

Yes, there is an option to configure the current delimiters separately along with the ID of the post where the new set of delimiters is used first. Currently this requires using configuration filters. Once that is done, new delimiters may be configured the usual way without affecting the older posts and pages.

Can I delimit sections for complements without using the block?

Yes, by ending the section with [anrghg_section] or any bracketed string that this code is configured to.

List labels tailored to the instance: _11=|Notes of ‘%s’| and _12=|Our sources|, where %s is replaced with the post title;
Writing direction tailored to the instance: _21=|-1| in Note list, _22=|-1| in Source list, or _20=|-1| in both lists, where -1 is right-to-left, and 1 is left-to-right;
Collapsing behavior tailored to the instance: _31=|-1| for the Note list, _32=|-1| for the Source list, or _30=|-1| for both lists, where-1is expanded (and collapsible),1is collapsed (and expandable), and0` is uncollapsible;
Footer deferral: _40=|1| or _40=|0| for whether this instance must be deferred to the footer, or must not be deferred.

Could multipage posts display all notes at the end?

Multipage posts are reported not to be properly indexed, and they are not properly navigatable either, with page numbers at the bottom only, and no distinctive head zone for the extra pages. Thus, ‘Page break’ is a bogus feature and should never be used.

Being able to read the whole content merely by scrolling is much more user friendly. Consistently, implementing anything specifically for multipage posts would be wasting the time of all involved parties, which is why WordPress did not properly implement its multipage feature in the first place.

How to reset the settings to default values?

The easiest way is to import an empty file.

Alternatively, deleting the ‘anrghg’ row in the ‘wp-options’ table in the database has the same outcome.

Why do setting descriptions not display in tooltips only?

Info hover buttons would cause issues for either accessibility or keyboard navigation.

Thanks to the ‘Save settings’ button being constantly visible at the bottom of the window, the settings are not spatially constrained.

The settings page is mostly visited at setup, while information is wanted, less often later on.

Nevertheless, the settings page verbosity is configurable at three levels, one of which is with information expand buttons. Another option fully hides almost all explanatory information.

▶ The setting for inclusion of generated list labels in the table of contents has been moved from ‘Notes and sources’ to ‘Table of contents’, and it now includes ‘Reference lists’. As a consequence, the key name needed to be changed and its meaning inverted.

Hoping that the new design is more convenient, we apologize for the change.

▶ In expectation of the oncoming Reference list block that may be used to configure collapsible Reference lists as well as short bibilographies and ‘Further reading’ boxes, the word ‘References’ is now being avoided when referring to ‘Notes and sources’. For consistency, intuitivity and ease of maintenance also with respect to users of configuration filters, all related setting keys need to be changed, and the code name of the related block should also be updated since it appears in the post source text and may be used in an automatically added class name, and block-internal attribute names because of their output in markup for storage purposes. Existing blocks keep working but are not editable. Legacy notes-and-references blocks may be converted to HTML by clicking ‘Keep as HTML’ in order to copy the values to a new instance of the block. We apologize for the disruptions, underscoring that the plugin is still declared as in development.

0.50.0 (2022-01-07)

▶ Two setting keys needed to be renamed because their names were confusing, while they may be read by users of string translation panes or configuration filters: anrghg_list_aria_label_notes to anrghg_list_label_aria_notes, and anrghg_list_aria_label_references to anrghg_list_label_aria_references. For 0.50.1, as this notice is added—apologies for delay—, two other keys need to be renamed because their names were misleading: anrghg_tooltip_read_more_link_text_note to anrghg_complement_tooltip_list_link_text_note, and anrghg_tooltip_read_more_link_text_reference to anrghg_complement_tooltip_list_link_text_reference. In the same move, several keys used in the ‘Notes and sources’ feature, including the first two, are renamed for consistency and completeness to improve intuitivity and user experience with configuration filters. For 0.50.2, _complement in the two keys above is replaced with the moved _note or _reference. We apologize for the inconvenience and hope that the improvements outweigh the trouble of reconfiguring existing installations.

▶ The setting keys anrghg_meta_box_complements_dir and anrghg_meta_box_list_footer_deferral needed to be renamed to anrghg_meta_box_complements_writing_direction and anrghg_meta_box_complement_list_footer_deferral respectively, for clarity, to improve maintainability. Since their default value is 0, the eventually checked checkboxes will be unchecked again, and the settings disappear from the meta box, and conversely for anrghg_meta_box_list_labels renamed to anrghg_meta_box_complement_list_labels. We apologize for the inconvenience.
